There have been some interesting updates over at SkyOS. First of all, it now has a VNC viewer, so you can control other computers from SkyOS. Another interesting addition are a set of VMWare tools; SkyOS now has full clipboard integration with the host OS when running in VMWare. Also added is seamless mouse integration, so you can just move your mouse to the edge of the VMWare window, and it will automatically ungrab it. There have been more changes, you can see the most prominent on SkyOS's website. For the under-the-hood changes, see the changelog.

I had a look at the screenshots and I don't see it as being designed after OS X. Besides the icons in a toolbar type widget at the bottom of the screen I'm really not seeing any special resemblance. If you see something I don't feel free to point it out.

I suppose the toolbar on the top does resemble the one from OS X to some slight degree.
